` JOHN EYRE o. HOLMES, or o'rfrnwA, oNrARro, CANAD ELECTRIC HEATER.

certain new and yuseful AImprovements inV Electric Heaters; and I doherebyfdeclare that the following visa full, clear, and exactdescription thereof. f f

lI-Ieretofore inelectricy heating apparatus it has beenextremelydiiicult to obtain an ei-KV cient heat radiation and at thesame time diffuse humidity; such a heater moreover has never tomyknowledge been obtained wherein one material provided atthe same time'the body,` ,the support yandz insulation yffor the wires and the.moisture container, andV my` invention has for its object to providesuch an apparatus possessing also beautydue to the material used, itsfashioning and to the effect of the .incandescent heating elements uponit.v Tothis end my invention consists of a heat radiating body having.electric re-4 sistant elements housed therein, the body while beingcapable of heat radiation being also a non-conductor, of electricityandsubstantial enough to carry alone the heating element. In order toprovide the qualities of a humidifier a receptacle for containing wateris formed in the body, and in order to impart to the structure thequality of a radiator and at the same time adapt it to have its beautyenhanced by the incandescence of i lthe heating elements I construct thebody of ,pose of illustration;

a clay compound molded and fired. The material I use for my heatradiator consists of re clay mixed withfire brick and oXids or otherclays for giving the desired color or colors and the proportion of fireclay and fire brick is twenty per cent. of fire brick to eighty percent. fire clay for comparatively heavy-articles and the proportions arevaried with the size and thickness of the article. The mixture is moldedand fired in the usual way.

For full comprehension, however, of my invention reference must be hadto the accompanying drawings in which similar reference charactersindicate the same parts, and wherein:

.n F 3 is ahorizontal sectional view taken on line Ele-3 Fig. 1,;.and

r Figfi is a horizontal sectional view taken OnlineLL-t Fig. 1.- f Y .Asbefore mentioned it is extremely dithcult to obtain an electric'lheaterwhich will be efficient and; at the same time ornamental. In ordertoobtain efiiciency 'I construct a body of any desired form, of a claycompound fired. The preferred embodiment of my invention consists of `a.substantial rectangularhorizontal oblong body b, the upper portion-:ofwhich is made in the form of'a handlejo and cored so as to form achamber d, the'bottom of which presentsa pan d1 for containing water forevaporation. The body at either or both sides is formed with chambers f4for containing the heat-radiating-incanti/escient elementsjin, the formof helical coils, ,g ,of high resistance wire, the coils being zhousedin the clay and connected togetheryy alternately at the` topv andbottom, thus forming series connection. The wires n for connecting thecoils together are embedded in the clay asshown. particularly inFir-g.,A 11; 'A socket@ similar. to'those usually setjin` the ,wall maybe employedfor connection with an ordinary lamp socket by an extension pof any desired type. This body 1s supported on legs 7 which may be ofthe same material as the body or other material. These legs arepreferably comparatively vwide in order to afford stability and may berigdlyattached to the body.

The foregoing sets forth Ya heater constructed according to my inventionwhich because of its formation from the particular clay mentionedprovides a structure on which to carry the heating elements, presentseffective insulation between the electric conductors and radiates theheat of the incandescent coils, which heat permeates the entire body.Further when it is provided with a water pan the water insures a flow ofhumidity with the radiant heat waves and althou h in dwellings where theatmosphere has t e desired complement of moisture the water receptaclewithin the body is not required and consequently the heater may be madewithout it, without departing from the spirit of my invention, Iconsider it an important feature with certain atmospheric conditions.Another feature of my invention is the construction of the body in sucha manner that while being self-Supporting it is also humidheat radiant.It has been common practice in the past to employ porcelain or otherlike entire body without departing Vfrom thev spiritY of my invention.

lVhat I claim is as follows:

l. An electric heater consisting of a heat radiating clay body yhavingelectric heating coils. Y

2. An electric heater consisting of va heat radiating clay body withchambers, coils of high resistance wire housed within the chambers, andmeans electrically connecting the coils inseries.r Y '3. An electricallyoperative humid-heat radiating body with a Water receptacle andVelectrical heating coils for the purpose of generating and radiating thehumid heat.

4. In an electric heater a self-supporting bodylconsistingof a clayinsulator having an integral handle and chambers in which electricalheating elements are housed.

f -5. In an electric heater a self-supporting oblong-upstanding bodyconsisting of a. translucent clay having'an integral handle' andchambersin the opposite sides thereof.`

6. In an electric heater'a selfesupporting oblong-upstanding bodyconsisting of a fired clay compound being anV electric insulator havingan integral handle and chambers inV the opposite sides'thereof.

n an electric heater a self supporting i oblong-upstanding bodyconsisting of a fired clay compound belng an electric insulator.

8. In an electric heater a self-supporting body consisting of a firedVclay having anin-'i tegral handle and chambers in which elecf tricalheating elementsarehoused and providing'insulation for them, the saidbody containing a water receptacle ing with the opening'of the handle.-

communicat-V 9. In an electric heater a self-supporting Yoblong-upstanding body consisting of a fired clay having an integralhandle and chambers in the vopposite sides thereof, the said ,body

containingV a water receptacle communicating with `the opening of thehandle.

Y V10,'AnV electrical insulated heat'radiator' consisting of a mixtureofire'clayan'd fire brick with color matter. v 11. 'An electricalinsulated heat radiator consisting of a mixture of re clay and lirebrick with color matter, re clay eighty per cent. fire brick Vtwentypercent. and color matter.V Y V In testimony whereof I'havelsigned `myname to this specification in the presence of two witnesses.
